SULKY.

To all whom it may concern:

Be it known that I, HENRY J. MILLER, a citizen of the United States,residing at North Paterson, Passaic county, and State of New Jersey,have invented certain new and useful Improvements in Sulkies, of whichthe following is a specification.

The object of my invention is to attain a light substantial andpractically rigid sulky, in so far as the rear portion of the sulky isconcerned; and the invention consists in the construction andarrangement of parts hereinafter described and claimed specific ally,distinguishing features being the use of compound braces at the bends ofthe lower bridge frame, in the use of an arch brace, the ends of whichare supported upon the lower bridge bar above the said compound bracesand reinforce the upper bridge bar centrally underneath the seat securedthereto, in the use of a trussed cross bar between the thills and inadvance of the axle truss,

in the use of lateral braces for the thills attached to the inner sidesthereof and to said trussed cross bar and the axle truss, and in the useof means for adjusting the ends of the upper bridge bar with relation tothe ends of the lower bridge bar, for the purpose of truing the wheels,all as hereinafter set forth.

In the accompanying drawings, Figure 1, is a top view of my improvedsullry; Fig. 2, a side elevation; Fig. 3, a sectional detail on plane ofline 33 Fig. 1, on an enlarged scale; Fig. 4, is a rear view of myimproved sulky taken on a plane at right angles to the axle truss; Fig.5, is a sectional detail of a portion of the axle truss upon an enlargedscale; Fig. 6, is a sectional detail of the cross brace; F ig. 7, is asimilar view showing a modification.

The wheels W, are mounted in the axle truss A, in the usual manner,thatis to say between the extremities of the upper and lower bridge bars a,a, which are held apart by the usual spacing stays a The bends of theinner bridge bar a, are stiffened and rendered practically rigid, eachby a compound brace B, consisting of the bow b, and truss rod 11,secured to the bridge bar a, by bolts 6 and spacing stays If, as will beunderstood more particularly by reference to Fig. 5. This reinforcementof the lower bridge bar a, renders it a substantial foundation or basefor the whole structure. An

Specification of Letters Patent.

arch brace C, the ends of which rest upon and are secured to thesereinforced bends or corners of the lower bridge bar a, reinforces theupper bridge bar a, centrally, immediately under the rear end of theseat S, which latter is secured directly to said bridge bar a, by screws8, or equivalent means,-the front edge of said seat being secured to thetrussed cross brace D, as illustrated in Fig. 3. This arch brace O,eifectually trusses the upper bridge bar a, and effectually supports anddistributes the weight of the driver resting on the seat S, acting as itdoes as a bridge or arch resting upon and connecting the re- Lnforoedcorners or bends of the lower bridge ar a.

The trussed cross brace D, consists of the cross bar cl, resting uponand secured to the upper sides of the thills E, and the truss d, securedto the under side of the thills, and centrally to the underside of thecross bar (Z, as shown in Fig. 6; in which the truss (Z, is reinforcedby a stiffener d; or as shown in Fig. 7, the truss d, with its stiffener(Z may constitute the essential portion of the trussed cross bar D, theupper bar d, being divided and secured to the truss (Z, or the structuremay be otherwise modified as may be found most expedient, the essentialfeature in this connection being the use of a trussed cross bar betweenthe thills and in advance of the axle truss A. The inner ends of thethills E, are attached to the axle truss A, at 6, above the compoundbrace B, aswell as to the trussed cross bar D, as before stated.

F, F, are lateral braces attached to the inner side of the thills E, tothe trussed cross brace D, and to the axle truss A, as shown in Fig. 1.Spacing stays f, f, are interposed between the lateral braces F, F, andthe thills E. These lateral braces F, stifien and reinforce the innerends of the thill so that the lateral vibration or sway is effectuallyprevented, and they also prevent the spreading of the rear portion ofthe thills in use.

The ends a, of the upper bridge bar a, are made adjustable withincertain limits with relation to the ends of the lower bridge bar a, byany suitable means, those shown in the drawings consisting of rods 7',secured to the lower bridge .bar a, and engaging with the upper bridgebar a, by means of set nuts 1*, r. This adjustment is for the purpose oftruing the hubs of the wheels on their axes,the requisite degree ofadjustment being very slight, and being amply provided for by the springor resilience of the ends a, of the upper bridge bar a.

By my construction and arrangement of parts I attain a light,substantial and practically rigid structure back of the point at whichthe forward ends of the lateral braces F, are secured to the thills E.The compound braces B, contribute largely to this result and aresupplemented in this respect by the arch brace C. The trussed cross barD, also performs an important function in that it affords means wherebythe lateral braces F, and other parts are effectually and rigidly boundtogether.

What I claim as my invention and desire to secure by Letters Patent is,

1. In a sulky, the combination with the axle truss, of compound bracesarranged to reinforce the bends of the lower bridge bar, each compoundbrace consisting of a bow and a truss rod, secured to said lower bridgebar, substantially as and for the purpose described.

2. In a sulky, the combination with the axle truss, of compound bracesarranged to reinforce the bends of the lower bridge bar, each compoundbrace consisting of a bow, and a truss rod secured to said lower bridgebar and spacing stays interposed bet-ween the bow and said bridge bar,for the purpose described.

3. In a sulky, the combination of an axle truss the bends of the lowerbridge bar of which are reinforced by compound braces each consisting ofa bow and a truss rod, and an arch brace interposed between the upperand lower bridge bars, the ends of said arch brace overlapping and beingsecured to the said reinforced bends of the lower bridge bar and thecentral portion of said arch brace being arranged to support the upperbridge bar, substantially in the manner and for the purpose described.

4. In a sulky, the combination of the axle truss, compound bracesarranged to reinforce the bends of the lower bridge bar, each com poundbrace consisting of a bow and a truss rod secured to said lower bridgebar, and an arch brace interposed between the upper and lower bridgebars, of the truss, the ends of said arch brace resting upon the lowerbridge bar above said compound braces, and the center of said arch braceresting against the upper bridge bar, substantially in the manner andfor the purpose described.

5. In a sulky of the character designated, the combination with theupper and lower bridge bars, of the axle truss, means for adjusting theends of the upper bridge bar with relation to the ends of the lowerbridge bar by utilizing the resilience of the upper bridge bar, saidmeans of adjustment being interposed between the bends and the ends ofsaid upper and lower bridge bars of the truss, substantially in themanner and for the purpose described.

6. In a sulky, the combination of the axle truss, comprising an upperand lower bridge bar and connections, the thills attached to the upperbridge of the axle truss, a truss cross bar secured to the thills inadvance of the axle truss, and lateral braces secured at their forwardends to the inner sides of the thills and at their rear ends directly tothe upper bridge bar of the axle truss, said lateral braces being alsosecured intermediately to the said truss cross bar, for the purposedescribed.
